Description

  The present invention relates to a navigation device, and more particularly to a navigation device suitable for correcting POI (Points Of Interest) information such as landmarks.

  Conventionally, in-vehicle navigation devices have displayed POI information such as landmarks of facilities in an overlapping manner on a map on a navigation screen.

  Also, such POI information is used as a destination set by the user during navigation, or for searching for a point (service search) where the user wants to stop by before the vehicle arrives at the destination. It was supposed to be used.

  Conventionally, many models have been adopted as navigation devices having a function capable of correcting such POI information.

  As an example, for example, the POI information is displayed in an editable state on the display unit, the POI information correction candidates are displayed in a state that can be selected by the user via a touch panel, and the selected correction candidates are displayed. The POI information is corrected by replacing the POI information to be corrected.

  Further, such correction of POI information has been made possible by the navigation device having a storage device that stores the data of POI information in a rewritable state.

It becomes possible to select promptly.

  The navigation apparatus according to the present invention is characterized in that the display control means performs control for preferentially displaying the same type of POI information as the POI information to be corrected as a correction candidate.

  According to such a configuration, the same kind of POI information as the POI information to be corrected is preferentially displayed as POI information that is likely to be replaced with the POI information to be corrected by the control of the display control means. This allows the user to select desired POI information more quickly.

  Further, the navigation device according to the present invention is characterized in that the display control means controls the POI information to be corrected so that it is not displayed as a correction candidate.

  According to such a configuration, it is possible to avoid displaying POI information that is meaningless as a correction candidate by preventing the corrected POI information from being displayed as a correction candidate by the control of the display control means. The user can more easily select desired POI information.

  According to the navigation apparatus of the present invention, the POI information that is highly likely to be replaced with the POI information to be corrected is preferentially displayed as a correction candidate under the control of the display control means, so that the user can obtain desired POI information. As a result of being able to make a quick selection, it is possible to reduce the labor required for correcting the POI information and to easily correct the POI information.

  Further, according to the navigation device of the present invention, the POI information of the same type as the POI information to be corrected is preferentially displayed as the POI information that is likely to be replaced with the POI information to be corrected by the control by the display control means. As a result, the user can select desired POI information more quickly. As a result, the POI information can be corrected more easily.

  Furthermore, according to the navigation device of the present invention, by preventing the POI information to be corrected from being displayed as a correction candidate by the control of the display control means, it is possible to avoid displaying POI information that has no meaning as a correction candidate. As a result, the user can more easily select desired POI information. As a result, the POI information can be more easily corrected.

  That is, in the present embodiment, among various data stored in the storage unit 7, at least the display on the map on the navigation screen, the setting of the destination, or the own vehicle arrives at the destination. The POI information (hereinafter referred to as “use state POI information”) used for searching for a point where the user wants to stop by (service search) or the like can be rewritten.

  As shown in FIG. 2, an operation screen 11 on which various input operations can be performed via the input operation unit 2 can be displayed on the display unit 3 based on the drawing data created by the drawing unit 8. It is said that.

  On the operation screen 11, “POI information correction” can be selected as one of the operation items 12.

  When “POI information correction” is selected by the operation of the input operation unit 2 by the user, the selection result is input to the control unit 6 via the interface 5 as an input signal.

  In response to the input signal, the control unit 6 outputs a command to the drawing unit 8 to create drawing data of a POI editing screen that can edit the POI information stored in the storage unit 7. It is like that.

  Based on this command, the drawing unit 8 generates drawing data for the POI editing screen and outputs it to the display unit 3.

  The display unit 3 converts the drawing data of the POI editing screen output from the drawing unit 8 into an image and displays the POI editing screen.

  This POI editing screen displays, for example, a list of use state POI information together with point information (address, etc.) of each use state POI information, and desired use state POI information that the user desires to correct from this list. That is, the POI information to be corrected may be selected by operating the input operation unit 2.

  In addition, the POI editing screen is not limited to this, and the icon of the usage state POI information displayed on the map remains in the map display state, and the touch of the cursor or fingers via the input operation unit 2 (touch panel method) The POI information to be corrected may be selected by selecting (by limiting to).

  When POI information to be corrected is selected by the user operating the input operation unit 2 on the POI editing screen, an input signal corresponding to the selected POI information to be corrected is transmitted via the interface 5 to the control unit. 6 is input.

  When the control unit 6 confirms that the POI information to be corrected is selected by the input of this input signal, the control unit 6 gives the drawing unit 8 a new POI information to be replaced with the POI information to be corrected as the next stage POI editing screen. A command to create correction candidate drawing data for displaying a POI information candidate (correction candidate) in a selectable state by an operation of the input operation unit 2 is output.

  The storage unit 7 stores the correction candidate data, and the control unit 6 refers to the correction candidate data and outputs a command to create the correction candidate drawing data. It has become.

  Based on the command of the control unit 6, the drawing unit 8 creates the correction candidate drawing data and outputs the created correction candidate drawing data to the display unit 3.

  As a result, for example, as shown in FIG. 3, the display unit 3 includes a plurality of POI information (POI information 1, POI information 2,...) As correction candidates 15 together with an icon 14 of POI information to be corrected. Are displayed in a selectable state by the operation of the input operation unit 2.

  When the user selects specific POI information from the correction candidates 15 displayed on the display unit 3 by operating the input operation unit 2, an input signal corresponding to the selected new POI information is input to the interface 5. Via the control unit 6.

  When the input signal corresponding to the selected new POI information is input, the control unit 6 stores the new POI information in the storage unit 7 as new usage state POI information.

  As a result, the POI information to be corrected, which has been stored in the storage unit 7 as the usage state POI information so far, is rewritten to the new usage state POI information, and the POI information is corrected.

  Then, on the premise that the POI information can be corrected in this way, in the present embodiment, the POI information that is likely to be replaced with the POI information to be corrected by the control unit 6 functioning as display control means. Is controlled so as to be preferentially displayed as the correction candidate 15.

  That is, the control unit 6 instructs the drawing unit 8 to create correction candidate drawing data for displaying the POI information that is likely to be replaced with the POI information to be corrected at the head of the correction candidate 15. Is output.

  As a result, the POI information that is likely to be replaced with the POI information is preferentially displayed on the display unit 3 as the correction candidate 15, so that the user can quickly obtain the desired POI information as new POI information. It becomes possible to select.

  Furthermore, in the present embodiment, the control unit 6 preferentially displays the same type of POI information as the POI information to be corrected as the correction candidate 15 as the POI information that is likely to be replaced with the POI information to be corrected. Control is to be performed.

  That is, the control unit 6 displays the same type of POI information as the POI information to be corrected at the head of the correction candidate 15 as the POI information that is likely to be replaced with the POI information to be corrected. A command to create correction candidate drawing data for this purpose is output.

  As a result, for example, as shown in FIG. 4, the display unit 3 has a convenience store icon (convenience store A) as an example of POI information to be corrected and a POI to be corrected at the head of the correction candidate 15. Store names (convenience store B, convenience store C, convenience store D,...) Of a plurality of convenience stores that are POI information of the same type as the information are displayed in a selectable state by operating the input operation unit 2.

  Here, as described above, stores such as gas stations, convenience stores, and family restaurants often have the same type of POI information as the POI information to be corrected because stores of the same type as the previous store often enter when stores are replaced. It can be said that the POI information is likely to be replaced with the POI information to be corrected.

  Therefore, by displaying preferentially the same type of POI information as the POI information to be corrected, the user can more quickly select desired POI information as new POI information.

  Further, in the present embodiment, the control unit 6 performs control so that the POI information to be corrected is not displayed as the correction candidate 15.

  That is, the control unit 6 outputs a command for creating correction candidate drawing data that does not display the POI information to be corrected as the correction candidate 15 to the drawing unit 8.

It becomes possible to select POI information.

  The control unit 6 has various functions necessary for navigation in addition to the function as display control means.

  For example, the control unit 6 reads out the map data stored in the storage unit 7 and outputs a command for creating map drawing data for displaying a map necessary for navigation to the drawing unit 8 together with the map data. It has become. Accordingly, map drawing data is created by the drawing unit 8, and the created map drawing data is output to the display unit 3, whereby the map is displayed on the display unit 3.

  Further, when the user sets a destination by operating the input operation unit 2, the control unit 6 calculates a route to the destination, and moves the vehicle to the destination along the route calculated by the route calculation. A command to create guide image data necessary for guidance is output to the drawing unit. Thereby, guide image data is created by the drawing unit 8, and the created guide image data is output to the display unit 3, so that a guide image such as an enlarged intersection view is displayed on the display unit 3. It has become.

  Further, the control unit 6 outputs a command to the voice data creation unit 9 to create voice data necessary for guiding the vehicle to the destination along the route calculated by the route calculation. Yes. As a result, voice data is created by the voice data creation unit 9, and the created voice data is output to the voice output unit 4, whereby guidance voice is output from the voice output unit 4.

  Moreover, the control part 6 acquires the own vehicle position which the own vehicle position detection part 10 detected, and performs the map matching which matches the own vehicle position on the road shape data in map data.

  When navigation is performed using the navigation device having the above configuration, the new usage state POI information rewritten by correcting the POI information is displayed on the map on the navigation screen, the destination set by the user, Alternatively, it is used for service search or the like.

  Therefore, according to the present embodiment, the POI information that is likely to be replaced with the POI information to be corrected by the control of the control unit 6 is preferentially displayed as the correction candidate 15 so that the user can obtain the desired POI information. You can select quickly.

  As a result, the labor required for correcting the POI information can be reduced, and the POI information can be easily corrected.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible as needed.

  For example, in the above-described embodiment, a convenience store is exemplified as the same type of POI information as the POI information to be corrected. However, the present invention is not limited to this, and the POI information is also used when the POI information is a gas station or a family restaurant. The present invention can be effectively applied.
